| 摘 要： | Based on the sequential probability ratio test （SPRT） developed by Wald, an improved method for successful probability test of missile flight is proposed. A recursive algorithm and its program in Matlab are designed to calculate the real risk level of the sequential test decision and the average number of samples under various test conditions. A concept, that is ＂rejecting as soon as possible＂, is put forward and an alternate operation strategy is conducted. The simulation results show that it can reduce the test expenses.
